SOLUTION FOR WATERPROOFING FABRICS.

1,240,3d5. No Drawing.

To all whom it may comerm Be it known that I, TrroMA's 0. James, acitizen of the United States, and a reeldent of Chicago, in the countyof Cook and have invented certaln new and useful Improvements-inSolutions for Waterproofing Fabrics; and I do hereby declare that thefollowing is a' full, clear, and exact description thereof.

This invention relates to. an improved solution forwater-proofingfabricsand consists of the matters hereinafter despribedand more articularly pointed out in the appended c aim.

The object of my invention in to produce a mixture or preparation forthe purpose of water proofing fabrics, superior to the preparations nowin use, which may be prepared with ease and at considerable less costthan the cost of preparations now used for snmlar purposes.

In carrying out my formula I make a mixture of on -half pound of acetateof lead and one-half pound of powdered alum, with three gallons ofwater, and place the same in tatedor stirred until the acetate of leadand the alum is thoroughly dissolved therein, after which the solutionis left at rest for a suitable length of time, to permit of the depositof sediment on the'bottom of the vessel. The solution or mixture in thevessel is then withdrawn by means of a siphon or any suitable devicewhich will not disturb the sediment in said vessel, and is then measuredand placed in a second vessel provided therefor.

For each gallon of the drawn ofi mixture and in proportionate amountsfor each proportionate part of a. gallon, I add one ounce of gum arabicwhich has been dissolved in benzin or a similar hydrocarbon or in analcoholic body such as wood alcphol. The gum arabic may be dissolved many other volatile chemical which is not in itself oleaginous or greasy.

The water-proofi g mlution is now ready 1 Specification of LettersPatent.

for use and the manner of applying it to the fabric for the purpose ofmaking 'the latter impervious to Assuming the fabric to be in the bolt,said bolt is immersed in the solution and when thoroughly saturated orimpregnated, the bolt of fabric is removed from the solution and passedthrough a suitable compressing or wringing device to expel all thesurplus solution therefrom. Thereafter the fabric may be dried byartificial means or by exposure to the atmosphere.

The solution may be applied equally as well to a ready made garment asto fabric in the bolt. In the case of a coat, uniform or the like, forexample, the garment is laid out fiat upon a table or other suitablesurface, and then saturated with the solution by a sponge or'rag whichhas been 7 or by other suitable means, by movingthe wet sponge or ragover the garment in the manner in water is as follows:

which a tailor wculd dampen a garment After been thus treated with thewater proofing solution, the garment may be hung up to dry either in adrying room or in the atmosphere.

Fabrics after having been water-proofed with my improved solution,retain their original color and shape and the presence of thewater-proofing solution is not noticeable in the fabric even upon closeinspection of the same. Any fabric, whether woven or knitted, regardlessof its texture, may be so treated to make the same water proof.

' Garments, after being treated with my 1mbe worn without any provedsolution may discomfort to the wearer, so thoroughly does the solutionimpregnate the texture, and make the samethoroughly water-proof.Exposure to the rain for hours will not change the fabric, so eficientlywill the water-proofing shed the rain'and "moisture. It is also to'benoted that m improved solution is not only highly e cient in use butpossesses other very desirable elements of utility, namely cheapnessandsimplicity m its preparation and in its application to fabrics.

Garments which have been treated with my improved water-proofingsolution beside possessing the advantages above mentioned, are r nderedpractically in mmable i and may also be pressed in the manner of acetateand.

alum of g um arabic dissolved in an alcoholic body.
